To all whom it may concern Be it known that I, ALFRED G. F. SKI, a citizen of the United States, residing in the borough of Brooklyn, city of New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

This invention relates to web coiling devices applicable to typewriting machines wherein it is desired to maintain the printed web intact after it is fed from the platen.

In my Patent No. 1,069,149, dated August 5, 1913, on which this invention is an'improvement, several webs are fed together around the platen, the bills forming one web being torn off one by one to accompany the purchases, while the copy web is carried rearwardly to a spool or reel on which it is coiled.

One object of this invention is to improve the manner of coiling the fragile web, and to avoid injury thereto, to which end I lead the web through a guide which is automatically adjusted by causing one end thereof to press against or ride upon the winding roll, whereby the incoming web is straightened prior to coiling on the roll; and as the diameter of the roll increases, the web is directed or guided to the circumference thereof, without liability of kinking or bending. Advantage is also taken of the pressure of the adjustable guide against the roll to aid the web in coiling snugly, and also to constitute a brake to prevent the web from uncoiling accidentally.

In the accompanying drawings, Figure 1 is a perspective view, partly broken away, illustrating the invention. Fig. 2 is a cross section, showing the invention used in connection with an Underwood writing machine. Fig. 3 is a sectional view through the spool and guide, dotted lines indicating the adjustability of the guide as the coil of the web increases in diameter. Fig. 4.- is a detail view of the spool. the coiled web being shown in dotted lines. Fig. 5 is a perspective view of the leading end of the web, folded to facilitate its attachment to the winding spool. Fig. 6 is a detail perspective view of the removable head and a portion of the spindle, disassembled.

Paper rolls 1 and 2 are mounted on shafts 3 and 4, the webs 5 and 6 being led from the KU R0 w rolls over the rounded head 7 of the paper shelf 8 of an Underwood writing machine, thence passing around the platen 9 (against which they are held by front and rear pressure rolls 10 and 11) and upwardly in front of the platen printing point. The leading ends of the webs may be folded as shown at 24 (Fig. 5), before introduction between the platen and the pressure rolls.

In the present instance, the web 5, leading from the paper roll 1, may comprise sales slips arranged in series, which are torn off successively as they are printed upon, to accompany the purchases. The web 6 constitutes a duplicate record, to be preserved, it being led backwardly from the platen 9, and wound upon a spool or reel 18, 19, 20, from which the coiled web may be removed from time to time.

The shafts 3, l. supporting the paper rolls. are mounted in a casing 12, relatively to which the platen 9 travels back and forth. said casing being closed by a cover 13 hinged at 14. The spool or reel 18, 19, 20, on which the web 6 is wound, may be journaled in the bracket arms 15. secured to the cover.

The web 6 is fed down the sloping cover 13 and between two parallel confining rods 16 extending between the arms 15, which rods not only coiiperate with the bracket arms 15 to direct the feed of the web, but also. by reason of their elevation above the surface of the cover 13, hold a part of the web off the cover (Fig. 2), thereby avoiding the necessity of subjecting the weak web to strain or wear by reason of its frictional engagement with the cover during the back and forth travel of the platen 9.

To eliminate tension on the reach 6 of the web between the platen and spool, owing to such relative movement between the platen and the spool or reel, the web is allowed to feed off the lower end of the sloping cover 13 to form a loose bight 17 (indicated in Fig. 2) before being led to the spool. Said spool comprises a spindle l8 journaled in the bracket arms 15 and having heads 19, 20, between which the web is (roiled. The spool is rotated by a crank 21, spring latches 22, pivoted at 23 to the arms 15. holding the spindle in place.

The leading end 24 of the web is easily and quickly fastened to the spool by slightly raising a springy clamping finger or catch 25 seated in a groove 26 extending about longitudinally of the spindle 18, between which finger and spindle, the leading end is inserted, the tension of the clamp crimping the paper into the groove. The clamping finger extends partway only across the spool. one end of the finger being fixed, and the opposite end being free; and the spindle has a finger recess 27 to enable the clamping finger 25 to be grasped and raised. By turning the crank, the spool is rotated to wind the web thereon.

To avoid or minimize the liability of the web being caused to snarl and wind unevenly on the spool, or becoming split 011 the edges, or torn across, the web is led up from the loose bight 17 over a supporting and guiding plate 28 swiveled or hinged on a rod 29 carried by branch arms 30 extending from the bracket arms 15, said plate having lips 31 turned over along its side edges to overlie the plate and form ways in which the side edges of the web 6 slide. whereby the web is straightened out and guided to the spool. The introductory ends of the ways are outwardly flared, as at 32, to prevent injury to the web as it is drawn onto the guide, and to permit the web to be quickly coiled on the spool from time to time by turning the handle 21. The oppo site end of the plate is extended, as at 33, to form a follower, pressed against the circumference of the roll on the spindle by spring 34; and the web is led between the follower 33 and the roll in winding thereon, whereby as the diameter of the roll varies, in winding, the guide 28 will be rocked, so as to direct the web automatically to the circumference of the roll (Fig. 3). The follower 33, by pressing the roll of web 6, also causes the web to roll tightly about the spindle 18. and moreover prevents accidental unwinding.

When the web 6 on the spool, is to be removed, the latches 22 are thrown to inoperative positions, to release the spool to permit it to be dismounted from the bracket arms 15, after which one of the heads 20 (mounted on one end of the spindle and normally confined between a shoulder 35 on the spindle and one of the bracket arms 15) is removed. to enable the roll of printed web to be drawn endwise from the spindle. The leading end of the web slides from beneath the free end of the clamping finger 25 without mutilation.

The clamping finger protrudes from the spindle, and in order to avoid uneven winding of the web 6 on the spool, the hub 36 of the removable head 20 (said hub having the same circumference as the spindle and fitting on the reduced end 40 thereof), has a rib or support 37 projecting beyond its circumference to a height equal to that of the clamping finger 25, the w enough to bridge the both the clamping spindle 18 has the shoulder 35 hub 36 (Fig. 6) of the head 20 and insure that, in assen shall lie in line with The spool is the guide and th beneath the guide fall loosely and ac fed from the platen. so commode the operator. writing until the hausted before wi on the spool.
